PHOTOELASTIC STRESS ANALYSIS

The basic theory, use, and model construction for photoelastic stress analysis are briefly described. Kodak Limited, in an attempt to prove that this analysis method could be used on subjects other than static models, used high-speed photography to record a series of stress patterns through the polariscope. The model used was a rhythmical-load applied to a plastic cross section of a rail in order to simulate the passage of wheels across it. Individual still pictures were also taken by means of high-speed gas discharge lamps. A still photograph is shown of the photoelastic stress patterns in a cross-section of a British bull-head rail and chair.
